DEAR sir,
i want program in keil c for generating 250 pulses with a pulse width of 5sec in timer mode . iam using a 11.0592 MHz crystal oscillator.
cant help. my program can only do 249 pulses with a pulse width if 5sec in timer mode.
So you have 2 choices:
1. Do it yourself;
2. Pay someone to do it for you.
Note: if this is a school assignment, option 2 is usually frowned upon.
The big question: Do you see any real problems generating 250 pulses with a length of 5 seconds?
The next question - what will you do with the missing requirements - such as how long pause between the pulses. Setting the pause to zero will creatly simplify the problem - just generate a single 1250 seconds long pulse.
then help me with that 249 pulse with 5 sec width program.
Do you mean "help", or do you just mean "do it for me" ?
If "help", then what have you tried so far? where are you stuck?
For general help on using the 8051, see: http://www.8052.com/tutorial www.8052.com/.../120112 http://www.keil.com/books/8051books.asp
For help with Keil C51 specifically, see: http://www.keil.com/support/man_c51.htm http://www.keil.com/appnotes/list/c51.htm http://www.keil.com/download/list/c51.htm
If you just mean "do it for me", then how much will you pay?
248 is easy!!!
In fact, doing just one is not hard.
Doing any multiple is then easy...
